Cluster Mode Deployment

This Quick Start Manual is to help you quickly download, install and use Nacos on your computer to deploy the cluster mode for production use.

Cluster Deployment Architecture

Therefore, when it is open source, it is recommended that users put all server lists under a vip and then hang under a domain name.

Http://ip1:port/openAPI Directly connected to ip mode, the machine needs to be modified to use ip.

Http://SLB:port/openAPI Mount the SLB mode(Intranet, do not expose internet to avoid security risks), directly connect to SLB, the following server ip real ip, readability is not good.

Http://nacos.com:port/openAPI Domain name + SLB mode(Intranet, do not expose internet to avoid security risks), good readability, and easy to change ip, recommended mode

1. Preparing for the Environment

Make sure that it is installed and used in the environment:

64 bit OS Linux/Unix/Mac, recommended Linux system.
64 bit JDK 1.8+; Download. Configuration.
Maven 3.2.x+; Download. Configuration.
3 or more Nacos Nodes;

2. Download source code or installation package

You can get Nacos in two ways.

Download source code from Github

unzip nacos-source.zip
cd nacos/
mvn -Prelease-nacos clean install -U
cd nacos/distribution/target/nacos-server-1.3.0/nacos/bin

Download Compressed Packet after Compilation

Download address

Select the latest stable version from releases and download nacos-server-$version.zip or nacos-server-$version.tar.gz

  unzip nacos-server-$version.zip  OR tar -xvf nacos-server-$version.tar.gz
  cd nacos/bin

3. Configuration Cluster Profile

In the Nacos decompression directory Nacos / conf directory, there is a configuration file cluster. conf, please configure each line as ip: port.

# ip:port
200.8.9.16:8848
200.8.9.17:8848
200.8.9.18:8848

3.1 Open Default auth plugin (Optional)

Then Setting configuration file application.properties under conf.

Setting

nacos.core.auth.enabled=true
nacos.core.auth.system.type=nacos
nacos.core.auth.plugin.nacos.token.secret.key=${custom, make sure same in all nodes}
nacos.core.auth.server.identity.key=${custom, make sure same in all nodes}
nacos.core.auth.server.identity.value=${custom, make sure same in all nodes}

Detail see Authentication.

Attention，Default value in Document SecretKey012345678901234567890123456789012345678901234567890123456789 and VGhpc0lzTXlDdXN0b21TZWNyZXRLZXkwMTIzNDU2Nzg= is a public default, only should use in test temporary. Please make sure to replace it with another valid value when you actually deploy.

4. Determine The DataSource

Using built-in data sources

No configuration is required

Use an external data source

production and use recommendations at least backup mode, or high availability database.

Initializes the MySQL database

sql statement source file

application. properties configuration

application.properties configuration file

5. start server

Linux/Unix/Mac

Standalone mode

sh startup.sh -m standalone

Cluster mode

Using built-in data sources

sh startup.sh -p embedded

Use an external data source

sh startup.sh

6. Service Registration & Discovery and Configuration Management

Service registration

curl -X POST 'http://127.0.0.1:8848/nacos/v1/ns/instance?serviceName=nacos.naming.serviceName&ip=20.18.7.10&port=8080'

Attention: If open default auth plugin, please call with username and password in header.

Service discovery

curl -X GET 'http://127.0.0.1:8848/nacos/v1/ns/instance/list?serviceName=nacos.naming.serviceName'

Attention: If open default auth plugin, please call with username and password in header.

Publish configuration

curl -X POST "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test&content=helloWorld"

Attention: If open default auth plugin, please call with username and password in header.

get configuration

curl -X GET "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test"

Attention: If open default auth plugin, please call with username and password in header.

7. shut down server

Linux/Unix/Mac

sh shutdown.sh
